Abstract (en)
[origin: EP3442251A1] The present invention pertains to a method for providing a safe operation of subsystems within a safety critical system (SCS), wherein a malfunctioning subsystem of the SCS sends a malfunction signal to the other subsystems of the SCS including a one-time cryptographic key unique to the malfunctioning subsystem, which is then decrypted by the other subsystems and collective safety management is initiated when the cryptographic key is valid. The present invention relates particularly to traffic control systems, autonomous driving systems or automotive driver assistance systems. However, the present concepts are not limited to these applications and may be applied to various other applications as well. The solution of the present invention advantageously combines a swarm-like behavior of the subsystems collectively reacting to emergency situations with a one-time cryptographic authentication and/or authorization procedure preventing repeated manipulation of the system by the same perpetrator.
